Effective Bracing of Flexural Members and Systems in Steel Buildings and Bridges
This is the 2017 T.R. Higgins Lecture. Todd A. Helwig, PhD, professor of civil engineering at the University of Texas at Austin, will present his lecture that is focused on the stability of flexural systems in steel buildings and bridges with a particular emphasis on bracing requirements. The lecture highlights the results from large-scale experiments and parametric finite element analysis on flexural members. The many factors that impact the effectiveness of torsional bracing systems are covered. An overview of the system buckling mode for I-shaped girder systems, which is a relatively new failure mode the profession has become aware of over the past 15 years, is also discussed. Improved details such as the use of split pipe stiffeners and lean-on bracing are also covered.
This course is based on a past AISC Live Webinar.
